Gully Formation on Mars: Testing the Snowpack Hypothesis from Analysis of Analogs in the Antarctic Dry Valleys
Introduction: Gullies, a class of unusually young features on Mars consisting of an alcove, a channel and a fan, were initially interpreted to have originated through processes related to the presence of liquid water, primarily through groundwater discharge [1,2]; the current metastability of liquid water on the surface of Mars generated a host of alternative explanations for the gullies [see s...
متن کاملGully Formation on Mars and Earth: the Transition from Glacial Activity to Gully Depositional Phases
Introduction: The discovery of gullies on Mars [1,2] resulted in a wide variety of proposed candidate mechanisms for formation but ensuing analyses have shown very strong latitude and orientation dependencies on their distributions [3-6]. These constraints have been interpreted to require: 1) a volatile on or near the surface as a source of liquid water, and 2) insolation and slope orientation ...

Dickson) Gullies are extremely young erosional/depositional systems on Mars that have been carved by an agent that was likely to have been comprised in part by liquid water [Malin, M.C., Edgett, K.S., 2000.

متن کاملMars Gully Analogs in the Antarctic Dry Valleys: Geological Setting and Processes
Introduction: Malin and Edgett [1,2] initially described a class of young features on Mars that they termed gullies, consisting of an alcove, a channel and a fan. Restricted to middle and high latitude locations, these features were interpreted to have originated through processes related to the presence of liquid water (through groundwater discharge); the potential presence of liquid water on ...
متن کاملThe Effect of Varying Annual Snow Accumulation on Gully Formation in Anarctica: Comparisons between ‘wet’ and ‘dry’ Seasons and Implications for Gully Formation on Mars
Introduction: The discovery of gullies on Mars attracted significant attention because of the apparent role of liquid water in their formation and because of their very youthful nature [1,2]. They were initially interpreted to be the result of groundwater discharge [1-3], though further considerations regarding the current metastability of liquid water on the surface of Mars generated alternati...
